You have ten points for why muslims might not assimilate, and ten defeats you think matter, but never address the one idiocy of islam, and the one thing that it cannot resolve.
The problem of divine solidarity. Even good Aristotle, greek pagan who wanted to know God, understood this and cried willing to overcome it.
Solidarity is to know a man on his own terms and to be able to cry with him, and aspire with him. Aristotle said a king cannot have solidarity with a peasant. The king can make good national policy that does good for the peasant, and he can make the peasant rich this way, but he does not think like the peasant. And likewise, the peasant can feed a king's armies by doing well and having great crop yields and doing perfectly, but he doesn't know the mind of the king who needs these things. They do not understand one another. They lack solidarity, because solidarity is only had between equals.
Allah stands above as the king. The muslim below as the subject. The peasant. Neither really know each other, though. This is no different than the system aristotle cried under. And that system was paganism. For him, the most high was an unknowable, transcendent God above all things. But with no intermediary, it is unknowable. And so he lamented. The monotheos was unknowable to him.
Your islam does not solve that problem. Allah is still a remote God who knows not his people, nor do his people know him.
However, Christ is the incarnation of God. He is God become man that man might become God. That is, by the incarnation we know God and God knows us as people. He makes man and God equal so that we might have solidarity.
By having this bridge, man is able to intimately know the character of God, and by this also God also knows what it is to be man. By this, the issue of solidarity is solved. At this, man might be in union with God. At peace with God. In at-one-ment with God. This is our theosis, which is beyond all things islam teaches.
So I'd say your filthy desert-rat religion is nothing more than another paganism. It has 10 reasons to suck off european aid money, but not one reason why it brings man closer to God, while our Lord Jesus Christ does.
